The SSL certificate itself is not shared at install, once you've installed a regular ssl certificate, you can share it, through aliasing/rewrite/redirection/userdir tricks. But nothing about the certificate itself is shared. You just use a regular ssl certificate to share contents that belong to other web hosts on the same machine.

Well, to disguise instead of using my actual domain or having to register another domain for the other users who will use the shared SSL.

I never setup an ssl to be shared so I am asking for assistance

I'm pretty sure I don't understand you right, since the exact point of ssl is certifiying that an actual domain is the server that was registered for this one domain, disguising is something that SSL is supposed to PREVENT.
If you share your ssl, everyone is supposed to be able to see your domain in the certificate itself, that's a design goal and a design feature of SSL itself, SSL is meant to prevent your users from pretending to be you(so they can get sued instead of you if someone's money gets stolen).
How well it can be done in a world of clueless users is debatable, but the original design goals remain.
You can share an ssl withhttps://yourdomain.com/~user/
using the cpanel userdir tweak
or like I do, with mod_rewrite rewrite rules ashttps://yourdomain.com/otherdomain.com/user/
But there is no disguising. If it was possible, visa, MC, ebay and hotmail would be working on a new standard as we speak.
